Product Details
If you're working on a Gen-2 Hemi engine and need to replace your exhaust manifold gaskets, this set from Cometic is a solid option. These are Multi-Layer Steel (MLS) gaskets, which means they're built tough to handle the heat and pressure of performance engines without needing any extra sealants. They're designed to work well whether you have aluminum heads on an aluminum block or aluminum heads on a cast iron block, resisting the forces that can develop between different metals.
Cometic builds these gaskets with multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F and works great on various surface finishes. The center layer is uncoated stainless steel and can be varied in thickness to meet specific needs; in this case, they're .030 inches thick. The port size on these gaskets is 2.310 inches by 2.810 inches, designed to match the exhaust ports on Gen-2 Hemi engines.
This gasket set fits a range of classic Mopar vehicles, including models like the Dodge Charger, Plymouth Barracuda, and Dodge Challenger from the late 60s and early 70s. Make sure to check the fitment details to confirm compatibility with your specific vehicle.
